Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Assumes 4-layer PCB is used.

7.
Off is ≤ 0.8V and on is ≥ 2.4V for the MIC2545A-1 and MIC2549A-1. Off is ≥ 2.4V and on is ≤ 9.8V for the MIC2545A-2 and MIC2549A-2. The
enable input has about 100mV of hysteresis.
Guaranteed by design but not production tested.
